Effect of Electrolyte Concentration on the Viscosity and Voltammetry of Supercritical Solutions

measured for the first time using a modified quartz crystal
microbalance, and it is shown that ionic solvation leads
to a significant structuring of the solvent and an appreciable increase in solution viscosity. Voltammetric
investigations in the electrolyte solutions are used to
confirm the magnitude of the viscosity changes, and these
account for the appreciably lower than expected peak
currents.
